IMPROVEMENT IN CULTIVATORS.

Speoication forming part of Letters Patent No. 198,069, dated December 11, 1877; application led March 12, 1877.

To all whom it may concern: Y

Be it known that I, IRA BARBER, of La Porte, in the county of La Porte and State of Indiana, have invented certain Improvements in Gultivators, of which the following is a specification:

In the accompanying drawing, forming a part of this specification, Figure 1 is a plan of that part of the cultivator which embodies my invention. Fig. 2 is a vertical section x of Fig. l; and Fig. 3 is a perspective view of the bottom of the axleplate, hereinafter described.

Like letters indicate likeparts in all the gures.

In said drawing, A represents one fork of the tongue, B the arched axle, and C one of the carrying-wheels. D D are the two halves of 'the plow-beams, to which are attached the handle E and plow-standards F F. G is a crossbar extending across and attached to the forked ends of the tongue, and projecting beyond the same some distance on each side.

The pivot-post to which the plow-beams are at top and bottom, and the top end is inserted in a suitable bearing in the cross-bar, while the lower end is stepped in a metal plate, I, resting upon the horizontal part of the axle adjoining the wheel. As a cheap and eficient fasteningv for this plate, I perforate one end of it, so it may be slipped over the axle until its proper position is reached, as will be obvious from the drawing. rlhe other end is clamped .to the axle by bolts i i', passing through it and the flat end of the brace K, reaching down from the tongue to the under side -of the axle. A pivot, h, on which the plowbeams may through the ends ofthe beams and the pivotpost.

freely swing, is inserted` This form of joint between the beams and L is a latch-bar, attached to the upper end of the pivot-post, or to some part of the machine located as joint, which permits lateral -movement of the other extremity similar to that allowed the plows. The lower part of this latch-bar is liattened, as shown, and pin-holes s and a catch, s', are made therein. The flattened part passes through a cross bar or plate, m, inserted between `and secured in the two plow'- beams DD. Y

A latch-rod, n, is attached to the rear end of the attened part of the bar L, and reaches from thence up nearly to the curved part of the plow-handle, passing through an eye, n', projecting from the side of the handle, and its upper end is bent over, so as toserve as a handle, to be caught by the iinger of the operator when it is desired to release the catch s from the plate m.

When it is desired to hitch up the plows, it l is only necessary toraise them until the catch s engages against the plate m, which it does automatically 5 and it makes no diiferenee, with this operation, how near together or how far lapart the plows are at the time of being raised; and they may be swrmg laterally as well after being raised as before.

A pin is inserted in one of the holes s in the rear of the plate m. By this means I ix a limit to the depression of the plows, so that the depth'of the cut will be absolutely the same whether the ground is soft or hard. The extra holes are for the purpose of adj ustability in this regard.

A valuable feature of my invention lies in the fact that the plows, when thus sustained by the latch-bar, act as a counter-balance to the tongue, and maintain the latter in a level position.

The axle-plate is made to project over and cover the hub of the wheel, as shown, whereby it is made to act as a shelter or cover to the latter.

Having thus fully described my invention, what I claim as new is-,
